Trial summary

This pilot clinical trial studies the feasibility of a low glycemic load diet in patients with stage I-III colon cancer. A low glycemic load diet includes foods that have low scores on the glycemic index. The glycemic index is a scale that measures how much a certain carbohydrate causes a person's blood sugar to rise.

About this study

Official title: A Pilot Study to Determine the Feasibility of a Low Glycemic Load Diet in Patients With Stage I-III Colon Cancer

This pilot clinical trial studies the feasibility of a low glycemic load diet in patients with stage I-III colon cancer. A low glycemic load diet includes foods that have low scores on the glycemic index. The glycemic index is a scale that measures how much a certain carbohydrate causes a person's blood sugar to rise. A low glycemic load diet may help decrease the chance of cancer coming back and improve the survival in patients with colon cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the feasibility of following a low or medium glycemic load diet in patients with stage I-III (local-regional) colon cancer.

SECONDARY OBJECTIVES:

  1. To determine patient-reported acceptability of diet. II. To determine nutritionist resources utilized. III. To evaluate the effect of lowering dietary glycemic load on body mass index (BMI), lipid metabolism and pro-oncogenic intermediaries of cellular metabolism.

OUTLINE: Patients are sequentially enrolled in 1 of 4 possible cohorts as needed based on the feasibility of the prior cohort.

COHORT 1: Patients follow a low glycemic load diet with standard dietary intervention (contact with nutritionist in person every 2 weeks with phone contact on the alternating weeks) for 12 weeks.

COHORT 2: Patients follow a low glycemic load diet with intensified dietary intervention (contact with nutritionist in person every week) for 12 weeks.

COHORT 3: Patients follow a medium glycemic load diet with standard dietary intervention for 12 weeks.

COHORT 4: Patients follow a medium glycemic load diet with intensified dietary intervention for 12 weeks.

Being tested
questionnaire administration, laboratory biomarker analysis, Standard Dietary Intervention, Intensified Dietary Intervention, Low glycemic load

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • questionnaire administrationOther

    Ancillary studies including three day food record, twenty-four hour dietary recall, and a food acceptability questionnaire.

  • laboratory biomarker analysisOther

    Correlative studies

  • Standard Dietary InterventionBehavioural

    Participants will be contacted by a nutritionist, in person every 2 weeks with phone contact on the alternating weeks. At the initial visit, each participant will be given verbal and written patient education materials, including low glycemic load diet recipes, meal plans, food preparation, and grocery shopping information. Individual instruction will be tailored to their baseline dietary preferences (e.g. vegan, allergies, etc).

  • Intensified Dietary InterventionBehavioural

    Patients will be contacted weekly, in person, by a nutritionist . Participants will take part in a cooking demonstration at the time of their initial visit. The demonstration will be hands-on and participants will be able to sample foods and recipes. In addition to grocery shopping information, participants will be accompanied by a nutritionist to their local grocery store to practice new shopping habits for their target dietary glycemic load. Each participant will also receive weekly random phone calls to assess his or her progress.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Individual patient compliance, defined by following assigned target glycemic load index >= 75% of the time between weeks 4 and 12

    This compliance rate will be determined through conducting a 24 hour telephone recall, every 2 weeks at random and calculating the glycemic load. For each dose cohort, the number and percentage of patients who are compliant will be summarized, with 90% confidence interval that accounts for the two-stage design.

    Measured: Up to week 12

Secondary outcomes (2)
  1. Food acceptability score

    Results of the acceptability survey will be tabulated and described (the questions use a 7 point likert scale), separately for each cohort.

    Measured: Up to 12 weeks

  2. Hours of nutritionist time per week

    The median number of hours will be calculated based on time spent with each patient, separately for each cohort.

    Measured: Up to 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing questionnaire administration, laboratory biomarker analysis and Standard Dietary Intervention in people with Stage I Colon Cancer and Stage II Colon Cancer, run by Case Comprehensive Cancer Center at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Individual patient compliance, defined by following assigned target glycemic load index >= 75% of the time between weeks 4 and 12 (time frame: Up to week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2018.
